Revealing the Invisible Universe

Active Galactic Nuclei and Large-Scale Structures

Ryan Hickox, Dartmouth College

Abstract

Our understanding of the cosmic evolution of galaxies and supermassive black holes (SMBHs) has been revolutionized by the advent of large extragalactic surveys, which have enabled detailed statistical studies of galaxies, active galactic nuclei (AGN), and their host large-scale structures. I will give an overview of some recent results on SMBH and dark matter halo evolution, including the connection between AGN activity and star formation, and the links between galaxy growth, AGN, and their host dark matter halos. An exciting current observational frontier is studying the evolution of black holes and dark matter halos at redshifts of 2-4 and beyond, an exciting epoch that features the rapid assembly of cosmic structures. I will show how high-resolution, sensitive X-ray observations with Lynx will deliver a ground-breaking view of these early cosmic times, by probing the growth of black holes through AGN activity down to low masses and luminosities, as well as detecting and characterizing dark matter halos through the very first extended hot gaseous atmospheres.
